Title: SHIFT REGISTER UNIT AND DRIVING METHOD THEREFOR, GATE DRIVING CIRCUIT AND DISPLAY DEVICE
Abstract:
A shift register unit and a driving method therefor, a gate driving circuit and a display device, relating to the field of display technology. The shift register unit comprises: a first input module (101), for transmitting, under the control of a first input signal, a first voltage signal to a pull-up node (PU); an output module (20), for transmitting, under the control of a voltage signal of the pull-up node (PU), a clock signal to a first output terminal (Vz), and transmitting a second voltage signal to a second output terminal (Gn); a storage unit (30), with a first end connected to the pull-up node (PU) and a second end connected to the first output terminal (Vz); a first pull-down module (401), for pulling down the voltage of the first output terminal (Vz) and the voltage of the second output terminal (Gn), under the control of a first control signal; a second pull-down module (402), for pulling down the voltage of the first output terminal (Vz) and the voltage of the second output terminal (Gn), under the control of a second control signal; the first control signal and the second control signal being inverted signals with same frequency.
